TSQ2180/TSQ2280 deep hole drilling and boring machine
This is a kind of deep-hole drilling machine, which can do drilling, boring and trepanning of heavy workpiece with big diameter.
During the machining process, the workpiece rotates slowly and the tool rotates in high-speed and do feeding. It uses BTA internal chip removal during the drilling process.
During the boring process, the cutting fluid in the boring bar is supplied to the front (head of machine) of the boring tool, and the cutting fluid and chip are discharged.
The technology of extra chip removal is used during trepanning process, and the machine is equipped with special trepanning tools, tool holder and fixture. According to the needs of machining, the machine is equipped with drilling (boring) rod box. The tools can do rotating and feeding.
